摘要

VR-based methods for stroke rehabilitation have mainly focused on motor rehabilitation, but there is increasing interest towards the integration of cognitive training for providing more ecologically valid solutions. However, more studies are needed, especially in the definition of which type of content should be used in the design of these tools. One possibility is the use of emotional stimuli, which are known to enhance attentional processes. According to the Socio-emotional Selectivity Theory, as people age, this emotional salience arises for positive and neutral, but not for negative stimuli. Conversely, negative stimuli can be better remembered. In this study, we investigated the impact of using emotional stimuli with positive, negative and neutral valence in a VR cognitive and motor attention task. Ten stroke patients participated in a within-subjects experiment with four conditions based on the type of stimuli: abstract (control condition), positive, negative and neutral. The main task consisted of finding a target stimulus, shown for only two seconds, among fourteen neutral distractors. Eye movements were recorded with an eye-tracking system to investigate differences between conditions and in search patterns. Subsequently, a recall task took place and the patients had to identify all the target images among a valence-matched number of distractors. Our results corroborate the attention salience effect of positive and neutral stimuli in the VR task performance. Although we found no statistically significant differences between conditions in the recall task, there was a trend for recalling more negative images. This negative advantage comes at the expense of significantly more wrongly identified images/false memories for negative stimuli. Finally, we performed an analysis in which we relate performance scores with well-established cognitive assessment instruments, which supportsG the use of this approach both for assessment and rehabilitation purposes.
